Product Details

Features

  • Flexible stainless steel hose routes coolant between the radiator and engine
  • Includes three adapter sizes to match different radiator neck and outlet diameters
  • 48" length allows custom routing around engine bay obstructions
  • Chrome finish with matching aluminum clamp covers for a coordinated look

Description

This 48" chrome radiator hose kit connects the radiator to the water pump or engine block outlet, with flexible stainless steel construction that allows custom routing around engine bay obstructions rather than following a fixed factory hose shape. Three adapter sizes are included — 1 1/4", 1 1/2", and 1 5/8" — to match radiator necks and outlet ports of different diameters. Chrome finish and matching aluminum clamp covers give the installation a coordinated, finished appearance.

Confirm which adapter size matches your radiator neck and which matches your water pump or block outlet before routing, since the two ends of your installation may need different adapter sizes. Hose clamps and clamp covers are included.


Port and Adapter Sizing
This kit includes three adapter sizes — 1 1/4", 1 1/2", and 1 5/8" — since radiator necks and water pump/block outlets are often different diameters from each other. Confirm which size matches your radiator neck and which matches your water pump or block outlet before routing.

Routing and Length
The 48" overall length and flexible stainless steel construction allow custom routing around engine bay obstructions rather than requiring a fixed hose path. Confirm this length provides enough slack for your specific routing path before cutting or trimming.

Q&A

Why are there three different adapter sizes included?
The kit includes 1 1/4", 1 1/2", and 1 5/8" adapters to accommodate different radiator neck and water pump or engine outlet diameters, giving you multiple options for matching both ends of your cooling-system routing.

Does this kit include end caps?
No — this kit is designed to connect the hose to existing radiator and engine cooling-system ports using the supplied adapters. It's not intended as a block-off or capped-hose kit.

Does this kit include hose clamps and clamp covers?
Yes — the kit includes 4 hose clamps and 2 chrome aluminum clamp covers for securing the connections and providing a cleaner finished appearance.

Can I cut this hose to a shorter length?
Yes — the 48" hose can be trimmed for custom routing. Measure your complete routing path before cutting and leave enough length for proper adapter engagement, clamping, and bend clearance.
